The present inventionrelates to a cultivator sweep and has for its prime object to provide a structure which results in lighter draft andlp'erforms cleaner work than the ordinary well known sweep in use on garden plows.

Another very important object 'of themvention resides in the provision of a cultiva} tor sweep of this nature which is exceedingly simple in its construction, inexpensive to manufacture, strong and durable, thoroughlyeflicient and reliable in use, and otherwise well adapted to the purposefor which it is designed. V With theaboveand numerous other objects in view as will'appear as the'descriptionproceeds, the invention-resides in certain novel features ofconstruction, and in the combina tion and arrangement'of parts as willbe hereinafter more fully described andcl'aimed. 29 In the'drawingz Figure 1 is a side elevation of the; cultivator sweep embodying the features of my invention, and I iv r Y Flgures 2 and .3 aI'B'SGClHOIIELl v ews therethroughtaken substantially on the lines 2 and 33respectively of Figure 1. r i

Referring to the drawings in detail it will be seen that I provide a substantially V;-

shaped sweep A comprising a pair of in-;-

clined wings 5 which diverge 'rearwardly from each other from their front juncture the frontend of. which is in the form of a point 6. The wings'5areof a cross sectional shape which provides comparatively sharp 3 outer cutting edges; A knife "7 inclines upwardly and'forward from an a erturedarm-S which extends rear- .wardly and upwardly from the lower end of the knife and is bolted or'otherwise se-o cured as at 9 to the front or, apex portion of a the sweepA. This knife 7 is inclined up-' wardly and forwardly and is of an isosceles triangular cross sectional formation as is illustrated vto advantage in Figure 2. 1
